Seismic design of inelastic structures using equivalent linear system parameters: Part 2 - application and verification

Research output: Contribution to journalArticle

Abstract

In this second part of the two-part article, the incorporation of a set of equivalent linear system parameters derived in the preceding article in a direct displacement-based design (DDBD) method is presented. By using the proposed design procedures for reinforced concrete and steel, 16 structures modelled as single degree-of-freedom systems are designed. Their responses are then compared with those obtained from a dynamic inelastic time-history analysis. The results show that the use of the proposed equations to calculate ζeq and Teq and the incorporation of the proposed DDBD procedures to proportion structures will produce reasonably good results with relatively simple computation effort.
